NEW DELHI: The Supreme Court on Tuesday reserved its verdict on a batch of pleas challenging the validity of the 103rd Constitution amendment providing 10 per cent reservation to economically weaker sections (EWS) persons in admissions and government jobs.

A five-judge Constitution bench headed by Chief Justice Uday Umesh Lalit reserved the verdict on the legal question of whether the EWS quota violated the basic structure of the constitution after hearing a battery of senior lawyers including Attorney General K K Venugopal and Solicitor General Tushar Mehta in the marathon hearing that lasted for six-and-half-day.
